CISE Research Instrumentation: Large Shared Memory Compute and Visualization Server for Algorithm and Numerical Method Development

该合同将购买一个大型、共享内存、具有加速3d图形的多处理工作站，用于支持计算机和信息科学与工程的研究。该设备将用于几个研究项目，所有这些项目都需要在大型数据集上进行昂贵的计算。在下面列出的许多应用领域中，从二维建模跳到三维建模需要大量增加系统内存和CPU功率，而多个处理器之间共享的1gb内存将使许多三维模拟成为可能。在许多科学学科和其他图像处理应用中，可视化3d模拟结果也是一个主要挑战，需要显著的CPU功率和大内存；这种设备也适合这项任务。五个具体项目是：1)并行分子动力学计算，特别注意负载平衡；2)随机神经网络图像压缩；3)并行海声信号处理；4)将心脏组织兴奋模拟的双域方法扩展到三维；5)可视化和分析来自3-D超声机的大型数据集。＊＊＊

9422065 Board This award is to purchase a large, shared memory, multiprocessing workstation with accelerated 3-D graphics which will be dedicated to support research in computer and information science and engineering. The equipment will be used for several research projects, all of which require expensive computations to be performed on large data sets. The jump from two dimensional to three dimensional modeling in many of the application areas listed below requires a major increase in system memory and CPU power, and the 1 gigabyte memory shared between several processors will make many 3-D simulations possible. Visualizing the results of 3-D simulations in many scientific disciplines, and other image processing applications, is also a major challenge, requiring both significant CPU power and large memory; the equipment is suited to this task as well. Five specific projects are: 1) parallel molecular dynamics computations, with particular attention to load balancing; 2) image compression using random neural networks; 3) parallel ocean acoustic signal processing; 4) extension of bi-domain methods for simulation of excitations in cardiac tissue to 3-D; and 5) visualization and analysis of large data sets from a 3-D ultrasound machine. ***
